发明名称 Method and devices for laying a thread on a substrate in a zigzag pattern
摘要 In a method and device for applying a thread to a moving substrate, a thread is continuously dispensed to a pick-up point adjacent to the point of contact of two rotating wheels (2, 3) that are inclined towards each other. The peripheries of the wheels have fingers (7) which hook the thread and move it to one side or the other as the wheels rotate, and then deposit the thread extended between the fingers 180° from the pick-up point. Long spaces between the fingers (7) on one wheel or the other make it possible to lay the thread longitudinally (8b) or in a long diagonal line instead of merely in a lateral zigzag pattern. The method and device may be used to make an absorbent article, such as a diaper.
